Description
The initial missile used by the SA-N-12 system was the Buk-M1-2 (9M38M2) from the SA-N-7 system. This was 5.55 m long, had a body diameter of 0.4 m, and a launch weight of 710 kg. The minimum range was 3.5 km and the maximum range 30 km. The intercept envelope for this missile was between 30 m and 22 km. The SA-N-12 missile, designated 9M317( Buk-M2), is 5.55 m long, has a body diameter of 0.4 m and a launch weight of 715 kg. A 70 kg HE fragmentation warhead is fitted, but there is an option for a 50 kg warhead, which is probably an aimable HE warhead. The SA-N-12 missile is similar to the SA-N-7 but has shorter chord wings with a span of 0.86 m, is heavier and has a longer range. Propulsion for SA-N-12 is an integrated boost/sustainer solid-propellant motor that provides the missile with a peak velocity of 1.23 km/s. The missile has a minimum range of 3.5 km, and a maximum range of 42 km against a fighter aircraft target. The maximum range against SRBM is 20 km, which can be achieved at altitudes of between 2 and 16 km. The maximum range against small RCS cruise missiles and UAVs is between 20 and 26 km, at altitudes between 30 m and 6 km altitude. The maximum range against hovering helicopters is 42 km. The SA-N-12 missile has a surface warfare capability, with a minimum range of 3.5 km and a maximum range against ship targets of 25 km, and a maximum range against land targets of 15 km. Guidance in mid-course uses inertial plus command updates, and in the terminal phase uses a semi-active radar seeker. The missile has a storage life of 10 years in its canister, and uses a similar launcher to the SA-N-7.
